Several canals and foramens in the human orbit are well known in the literature. However, little is known about some minor canals or structures including metoptic canal and Warwick's foramen. The aim of the present study was to make morphometric measurements and to determine the incidence of the metoptic canal and Warwick's foramen in the Turkish population.
Ninety-two dried human skulls were examined. All skulls were obtained from the Turkish population and collection of the Anatomy Department of the Akdeniz University. The metoptic canal and Warwick's foramen were identified in the skulls. Incidence of these structures and diameters were determined. Morphometric measurements were made using various reference points in the orbit.
Of the 92 dry human skulls, the metoptic canal was detected in 20 of them. This canal was detected unilaterally. The metoptic canal was observed in 11 (11.9%) dry skulls in the right side, whereas it was observed in 9 (9.7%) dry skulls in the left side. There were no statistically significant differences according to the side for any of the measurements recorded (p>0.05). The Warwick's foramen was observed in 12 (13.0%) skulls of all dry skulls. This foramen was also present unilaterally and was right sided in 7 (7.6%) skulls and left sided in 5 (5.4%) skulls.
Determination of additional foramen in the orbit is contributed to the literature. The presence of the metoptic canal and Warwick's foramen and their relationship with other structures in the orbit may have clinical significance in surgical operations.
人体眼眶中的几条管和孔在文献中已广为人知。然而，对于一些较小的管或结构，如鼻额管和沃里克氏孔，人们了解甚少。本研究的目的是进行形态学测量，并确定土耳其人群中鼻额管和沃里克氏孔的发生率。
检查了92个干燥的人类头骨。所有头骨均来自土耳其人群，由阿克德尼兹大学解剖学系收集。在这些头骨中识别出鼻额管和沃里克氏孔。确定这些结构的发生率和直径。使用眼眶中的各种参考点进行形态学测量。
在92个干燥的人类头骨中，有20个检测到鼻额管。该管为单侧检测到。在右侧的11个（11.9%）干燥头骨中观察到鼻额管，而在左侧的9个（9.7%）干燥头骨中观察到。所记录的任何测量值在两侧之间均无统计学显著差异（p>0.05）。在所有干燥头骨中有12个（13.0%）头骨观察到沃里克氏孔。该孔也为单侧存在，右侧有7个（7.6%）头骨，左侧有5个（5.4%）头骨。
眼眶中额外孔的确定为文献做出了贡献。鼻额管和沃里克氏孔的存在及其与眼眶中其他结构的关系在外科手术中可能具有临床意义。
